FIELD OF THE INVENTION

This invention relates generally to novel5-substituted-indeno[1,2-c]pyrazol-4-ones which are useful as cyclindependent kinase (cdk) inhibitors, pharmaceutical compositionscomprising the same, methods for using the same for treatingproliferative diseases, and intermediates and processes for making thesame.

BACKGROUND OF THE INVENTION

One of the most important and fundamental processes in biology is thedivision of cells mediated by the cell cycle. This process ensures thecontrolled production of subsequent generations of cells with definedbiological function. It is a highly regulated phenomenon and responds toa diverse set of cellular signals both within the cell and from externalsources. A complex network of tumor promoting and suppressing geneproducts are key components of this cellular signaling process. Overexpression of the tumor promoting components or the subsequent loss ofthe tumor suppressing products will lead to unregulated cellularproliferation and the generation of tumors (Pardee, Science 246:603-608,1989).

Cyclin dependent kinases (cdks) play a key role in regulating the cellcycle machinery. These complexes consist of two components: a catalyticsubunit (the kinase) and a regulatory subunit (the cyclin). To date,nine kinase subunits (cdk 1-9) have been identified along with severalregulatory subunits (cyclins A-H).(A. M. Senderowicz and E. A. SausvilleJournal of the National Cancer Institute (2000), 92 (5), 376-387; and S.Mani; C. Wang; K. Wu; R. Francis; R. Pestell Exp. Opin. Invest. Drugs(2000) 9(8), 1849-1870).

Each kinase associates with a specific regulatory partner and togethermake up the active catalytic moiety. Each transition of the cell cycleis regulated by a particular cdk complex: G1l/S by cdk2/cyclin E,cdk4/cyclin D1 and cdk6/cyclinD2; S/G2 by cdk2/cyclin A and cdkl/cyclinA; G2/M by cdk1/B. The coordinated activity of these kinases guides theindividual cells through the replication process and ensures thevitality of each subsequent generation (Sherr, Cell 73:1059-1065, 1993;Draetta, Trends Biochem. Sci. 15:378-382, 1990)

An increasing body of evidence has shown a link between tumordevelopment and cdk related malfunctions. Over expression of the cyclinregulatory proteins and subsequent kinase hyperactivity have been linkedto several types of cancers (Jiang, Proc. Natl. Acad. Sci. USA90:9026-9030, 1993; Wang, Nature 343:555-557, 1990). More recently,endogenous, highly specific protein inhibitors of cdks were found tohave a major affect on cellular proliferation (Kamb et al, Science264:436-440, 1994; Beach, Nature 336:701-704, 1993). These inhibitorsinclude p16^(INK4) (an inhibitor of cdk4/D1), p21^(CIP1) (a general cdkinhibitor), and p27^(KIP1) (a specific cdk2/E inhibitor). A recentcrystal structure of p27 bound to cdk2/A revealed how these proteinseffectively inhibit the kinase activity through multiple interactionswith the cdk complex (Pavletich, Nature 382:325-331, 1996). Theseproteins help to regulate the cell cycle through specific interactionswith their corresponding cdk complexes. Cells deficient in theseinhibitors are prone to unregulated growth and tumor formation.

Protein kinases, in particular, CDK, play a role in the regulation ofcellular proliferation. Therefore, CDK inhibitors could be useful in thetreatment of cell proliferative disorders such as cancer, familialadenomatosis polyposis, neuro-fibromatosis, psoriasis, fungalinfections, endotoxic shock, trasplantaion rejection, vascular smoothcell proliferation associated with atherosclerosis, pulmonary fibrosis,arthritis glomerulonephritis and post-surgical stenosis and restenosis(U.S. Pat. No. 6,114,365). CDKs are also known to play a role inapoptosis.

Therefore CDK inhibitors, could be useful in the treatment of useful ofcancer; viral infections, for example, herpevirus, poxyirus,Epstein-Barr virus, Sindbis virus and adenovirus; prevention of AIDSdevelopment in HIV-infected individuals; autoimmune diseases, forexample, systemic lupus, erythematosus, autoimmune mediatedglomerulonephritis, rheumatoid arthritis, psoriasis, inflammatory boweldisease, and autoimmune diabetes mellitus; neurodegenerative disorders,for example, Alzheimer's disease, AIDS-related dementia, Parkinson'sdisease, amyotrophic lateral sclerosis, retinitis pigmentosa, spinalmuscular atrophy and cerebellar degeneration; myelodysplastic syndromes,aplastic anemia, ischemic injury associated with myocardial infarctions,stroke and reperfusion injury, arrhythmia, atherosclerosis,toxin-induced or alcohol related liver diseases, hematological diseases,for example, chronic anemia and aplastic anemia; degenerative diseasesof the musculoskeletal system, for example, osteoporosis and arthritis,aspirin-sensitive rhinosinusitis, cystic fibrosis, multiple sclerosis,kidney diseases and cancer pain (U.S. Pat. No. 6,107,305).

It has also been discovered that some cyclin-dependent kinase inhibitorscan be used in combination therapy with some other anticancer agents.For example, the cytotoxic activity of the cyclin-dependent kinaseinhibitor, flavopiridol, has been used with other anticancer agents incancer combination therapy. Cancer Research, 57, 3375 (1997).

Also, it has recenly been disclosed that CDK inhibitors may be useful inthe chemoprevention of cancer. Chemoprevention is defined as inhibitingthe development of invasive cancer by either blocking the initiatingmutagenic event or by blocking the progression of pre-malignant cellsthat have already suffered an insult or inhibiting tumor relapse (U.S.Pat. No. 6,107,305).

Furthermore, it has recently been discovered that cdk5 is involved inthe phosphorylation of tau protein, and therefore CDK inhibitors may beuseful in the treatment of Alzheimer's disease (J. Biochem., 117,741-749, 1995).

This body of evidence has led to an intense search for small moleculeinhibitors of the cdk family as an approach to cancer chemotherapy.There are no known examples of molecules related to the currentinvention which describe 5-substituted-indeno[1,2-c]pyrazoles as cdkinhibitors. There is one case describing indeno[1,2-c]pyrazoles havinganticancer activity. There are two other examples which describeindeno[1,2-c]pyrazoles having unrelated utilities and structures.

A series of indeno[1,2-c]pyrazoles having anticancer activity aredescribed in JP 60130521 and JP 62099361 with the following genericstructure:

No substitution is claimed on the indenophenyl portion of the moleculeand the molecules are not indicated to be cdk inhibitors. In addition,we discovered that substitution at the 5-position was critical for cdkinhibitory activity.

A series of indeno[1,2-c]pyrazoles having herbicidal activity aredescribed in GB 2223946 with the following generic structure:

The above compounds differ from the presently claimed invention in X_(n)is defined as halo, alkyl, haloalkyl, and haloalkoxy; n=0-2. Inaddition, R₁ is defined as acyl and R₂ is defined as alkyl orcycloalkyl.

A series of1-(6′-substituted-4′-methylquinol-2′-yl)-3-methylindeno[1,2-c]pyrazoleshaving CNS activity are described by Quraishi, Farmaco 44:753-8, 1989with the following generic structure:

Compounds of this series are not considered to be part of the presentlyclaimed invention.

As used herein, “pharmaceutically acceptable salts” refer to derivativesof the disclosed compounds wherein the parent compound is modified bymaking acid or base salts thereof. Examples of pharmaceuticallyacceptable salts include, but are not limited to, mineral or organicacid salts of basic residues such as amines; alkali or organic salts ofacidic residues such as carboxylic acids; and the like. Thepharmaceutically acceptable salts include the conventional non-toxicsalts or the quaternary ammonium salts of the parent compound formed,for example, from non-toxic inorganic or organic acids. For example,such conventional non-toxic salts include those derived from inorganicacids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric,nitric and the like; and the salts prepared from organic acids such asacetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric,citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic,benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric,toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, isethionic,and the like.

The pharmaceutically acceptable salts of the present invention can besynthesized from the parent compound which contains a basic or acidicmoiety by conventional chemical methods. Generally, such salts can beprepared by reacting the free acid or base forms of these compounds witha stoichiometric amount of the appropriate base or acid in water or inan organic solvent, or in a mixture of the two; generally, nonaqueousmedia like ether, ethyl acetate, ethanol, isopropanol, or acetonitrileare preferred. Lists of suitable salts are found in Remington'sPharmaceutical Sciences, 18th ed., Mack Publishing Company, Easton, Pa.,1990, p. 1445, the disclosure of which is hereby incorporated byreference.

The phrase “pharmaceutically acceptable” is employed herein to refer tothose compounds, materials, compositions, and/or dosage forms which are,within the scope of sound medical judgment, suitable for use in contactwith the tissues of human beings and animals without excessive toxicity,irritation, allergic response, or other problem or complicationcommensurate with a reasonable benefit/risk ratio.

The term “Pharmaceutically acceptable prodrugs” as used herein meansthose prodrugs of the compounds useful according to the presentinvention which are, within the scope of sound medical judgment,suitable for use in contact with the tissues of humans and lower animalswith undue toxicity, irritation, allergic response, and the like,commensurate with a reasonable benefit/risk ratio, and effective fortheir intended use, as well as the zwitterionic forms, where possible,of the compounds of the invention.

The term “Prodrugs”, as the term is used herein, are intended to includeany covalently bonded carriers which release an active parent drug ofthe present invention in vivo when such prodrug is administered to amammalian subject. Since prodrugs are known to enhance numerousdesirable qualities of pharmaceuticals (i.e., solubility,bioavailability, manufacturing, etc.) the compounds of the presentinvention may be delivered in prodrug form. Thus, the present inventionis intended to cover prodrugs of the presently claimed compounds,methods of delivering the same, and compositions containing the same.Prodrugs of the present invention are prepared by modifying functionalgroups present in the compound in such a way that the modifications arecleaved, either in routine manipulation or in vivo, to the parentcompound. The transformation in vivo may be, for example, as the resultof some metabolic process, such as chemical or enzymatic hydrolysis of acarboxylic, phosphoric or sulphate ester, or reduction or oxidation of asusceptible functionality. Prodrugs include compounds of the presentinvention wherein a hydroxy, amino, or sulfhydryl group is bonded to anygroup that, when the prodrug of the present invention is administered toa mammalian subject, it cleaves to form a free hydroxyl, free amino, orfree sulfydryl group, respectively. Functional groups which may berapidly transformed, by metabolic cleavage, in vivo form a class ofgroups reactive with the carboxyl group of the compounds of thisinvention. They include, but are not limited to such groups as alkanoyl(such as acetyl, propionyl, butyryl, and the like), unsubstituted andsubstituted aroyl (such as benzoyl and substituted benzoyl),alkoxycarbonyl (such as ethoxycarbonyl), trialkylsilyl (such astrimethyl- and triethysilyl), monoesters formed with dicarboxylic acids(such as succinyl), and the like. Because of the ease with which themetabolically cleavable groups of the compounds useful according to thisinvention are cleaved in vivo, the compounds bearing such groups act aspro-drugs. The compounds bearing the metabolically cleavable groups havethe advantage that they may exhibit improved bioavailability as a resultof enhanced solubility and/or rate of absorption conferred upon theparent compound by virtue of the presence of the metabolically cleavablegroup.

Preparation of Comounds of the Invention

It will be apparent to those skilled in the art that certain compoundsof formula (I) can exhibit isomerism, for example geometrical isomerism,e.g., E or Z isomerism, and optical isomerism, e.g., R or Sconfigurations. Geometrical isomers include the cis and trans forms ofcompounds of the invention having alkenyl moieties. It is well known inthe art how to prepare optically active forms, such as by resolution ofracemic forms or by synthesis from optically active starting materials.All chiral, diastereomeric, racemic forms and all geometric isomericforms of a structure are intended, unless the specific stereochemistryor isomer form is specifically indicated.

Such isomers can be separated from their mixtures, by the application oradaptation of known methods, for example chromatographic techniques andrecrystallization techniques, or they are separately prepared from theappropriate isomers of their intermediates, for example by theapplication or adaptation of methods described herein.

The compounds of the present invention are useful in the form of thefree base or acid or in the form of a pharmaceutically acceptable saltthereof. All forms are within the scope of the invention.

Where the compound of the present invention is substituted with a basicmoiety, acid addition salts are formed and are simply a more convenientform for use; and in practice, use of the salt form inherently amountsto use of the free base form. The acids which can be used to prepare theacid addition salts include preferably those which produce, whencombined with the free base, pharmaceutically acceptable salts, that is,salts whose anions are non-toxic to the patient in pharmaceutical dosesof the salts, so that the beneficial inhibitory effects on CDK inherentin the free base are not vitiated by side effects ascribable to theanions. Although pharmaceutically acceptable salts of said basiccompounds are preferred, all acid addition salts are useful as sourcesof the free base form even if the particular salt, per se, is desiredonly as an intermediate product as, for example, when the salt is formedonly for purposes of purification, and identification, or when it isused as intermediate in preparing a pharmaceutically acceptable salt byion exchange procedures.

According to a further feature of the invention, acid addition salts ofthe compounds of this invention are prepared by reaction of the freebase with the appropriate acid, by the application or adaptation ofknown methods. For example, the acid addition salts of the compounds ofthis invention are prepared either by dissolving the free base inaqueous or aqueous-alcohol solution or other suitable solventscontaining the appropriate acid and isolating the salt by evaporatingthe solution, or by reacting the free base and acid in an organicsolvent, in which case the salt separates directly or can be obtained byconcentration of the solution.

The acid addition salts of the compounds of this invention can beregenerated from the salts by the application or adaptation of knownmethods. For example, parent compounds of the invention can beregenerated from their acid addition salts by treatment with an alkali,e.g. aqueous sodium bicarbonate solution or aqueous ammonia solution.

Where the compound of the invention is substituted with an acidicmoiety, base addition salts may be formed and are simply a moreconvenient form for use; and in practice, use of the salt forminherently amounts to use of the free acid form. The bases which can beused to prepare the base addition salts include preferably those whichproduce, when combined with the free acid, pharmaceutically acceptablesalts, that is, salts whose cations are non-toxic to the animal organismin pharmaceutical doses of the salts, so that the beneficial inhibitoryeffects on CDK inherent in the free acid are not vitiated by sideeffects ascribable to the cations. Pharmaceutically acceptable salts,including for example alkali and alkaline earth-metal salts, within thescope of the invention are those derived from the following bases:sodium hydride, sodium hydroxide, potassium hydroxide, calciumhydroxide, aluminum hydroxide, lithium hydroxide, magnesium hydroxide,zinc hydroxide, ammonia, ethylenediamine, N-methyl-glucamine, lysine,arginine, ornithine, choline, N,N′-dibenzylethylenediamine,chloroprocaine, diethanolamine, procaine, N-benzylphenethylamine,diethylamine, piperazine, tris(hydroxymethyl)-aminomethane,tetramethylammonium hydroxide, and the like.

Metal salts of compounds of the present invention may be obtained bycontacting a hydride, hydroxide, carbonate or similar reactive compoundof the chosen metal in an aqueous or organic solvent with the free acidform of the compound. The aqueous solvent employed may be water or itmay be a mixture of water with an organic solvent, preferably an alcoholsuch as methanol or ethanol, a ketone such as acetone, an aliphaticether such as tetrahydrofuran, or an ester such as ethyl acetate. Suchreactions are normally conducted at ambient temperature but they may, ifdesired, be conducted with heating.

Amine salts of compounds of the present invention may be obtained bycontacting an amine in an aqueous or organic solvent with the free acidform of the compound. Suitable aqueous solvents include water andmixtures of water with alcohols such as methanol or ethanol, ethers suchas tetrahydrofuran, nitrites such as acetonitrile, or ketones such asacetone. Amino acid salts may be similarly prepared.

The base addition salts of the compounds of this invention can beregenerated from the salts by the application or adaptation of knownmethods. For example, parent compounds of the invention can beregenerated from their base addition salts by treatment with an acid,e.g. hydrochloric acid.

Pharmaceutically acceptable salts also include quaternary lower alkylammonium salts. The quaternary salts are prepared by the exhaustivealkylation of basic nitrogen atoms in compounds, including nonaromaticand aromatic basic nitrogen atoms, according to the invention, i.e.,alkylating the non-bonded pair of electrons of the nitrogen moietieswith an alkylating agent such as methylhalide, particularly methyliodide, or dimethyl sulfate. Quaternarization results in the nitrogenmoiety becoming positively charged and having a negative counter ionassociated therewith.

As will be self-evident to those skilled in the art, some of thecompounds of this invention do not form stable salts. However, acidaddition salts are more likely to be formed by compounds of thisinvention having a nitrogen-containing heteroaryl group and/or whereinthe compounds contain an amino group as a substituent. Preferable acidaddition salts of the compounds of the invention are those wherein thereis not an acid labile group.

As well as being useful in themselves as active compounds, salts ofcompounds of the invention are useful for the purposes of purificationof the compounds, for example by exploitation of the solubilitydifferences between the salts and the parent compounds, side productsand/or starting materials by techniques well known to those skilled inthe art.

Compounds according to the invention, for example, starting materials,intermediates or products, are prepared as described herein or by theapplication or adaptation of known methods, by which is meant methodsused heretofore or described in the literature.

Compounds useful according to the invention may be prepared by theapplication or adaptation of known methods, by which is meant methodsused heretofore or described in the literature, for example thosedescribed by R. C. Larock in Comprehensive Organic Transformations, VCHpublishers, 1989.

In the reactions described hereinafter it may be necessary to protectreactive functional groups, for example hydroxy, amino, imino, thio orcarboxy groups, where these are desired in the final product, to avoidtheir unwanted participation in the reactions. Conventional protectinggroups may be used in accordance with standard practice, for examplessee T. W. Green and P. G. M. Wuts in “Protective Groups in OrganicChemistry” John Wiley and Sons, 1991; J. F. W. McOmie in “ProtectiveGroups in Organic Chemistry” Plenum Press, 1973.

Preferred methods of synthesizing the compounds of the inventioninclude, but are not limited to, those methods described below. Each ofthe references cited below are hereby incorporated herein by reference.

An approach to preparing indeno[1,2-c]pyrazol-4-ones is presented inScheme 1 and can be used to prepare compounds of the present invention.The nitro group of dimethyl 3-nitrophthalate was reduced to the amineusing catalytic hydrogenation. The aniline was acylated using aceticanhydride and pyridine as a base. A mixture of the resulting acetamide 2and an acetophenone were treated with a strong base in an appropriatesolvent at elevated temperature to give the desired triketone 3.Additional means of preparing triketones are known to one skilled in theart as described in Kilgore et al, Industrial and Engineering Chemistry34:494-497, 1946, the contents of which are hereby incorporated hereinby reference. The triketone was treated with hydrazine at elevatedtemperature in an appropriate solvent to give theindeno[1,2-c]pyrazol-4-one ring system. Additional means of preparingindeno[1,2-c]pyrazol-4-ones are known to one skilled in the art asdescribed in Lemke et al., J. Heterocyclic Chem. 19:1335-1340, 1982;Mosher and Soeder, J. Heterocyclic Chem. 8:855-59, 1971;Hrnciar andSvanygova Collect. Czech. Chem. Commun. 59:2734-40, 1994 the contents ofwhich are hereby incorporated herein by reference. The amide wasdeacetylated by heating with a strong acid in an appropriate solvent togive aniline 4. This aniline was acylated under standard conditionsusing an acid chloride in an appropriate solvent to give the desiredproduct 5.

An alternative method for making compounds of the present invention isshown in Scheme 2. The intermediate triketone 3 can be deacetylated withstrong acid and reacylated with an appropriate acid chloride usingmethods known to those skilled in the art. Subsequently, triketone 6 canbe converted to the indeno[1,2-c]pyrazol-4-ones using the sameconditions described previously in Scheme 1.

Another method for preparing the triketones 6 of Scheme 2 employs thecondensation of a 1,3-diketone 6a with 3-nitrophthalic anhydride asdescribed in Rotberg and Qshkaya, Zh. Organ. Khim. 8:84-87, 1972; Zh.Organ. Khim. 9:2548-2550, 1973, the contents of which are herebyincorporated herein by reference. The 1,3-diketones, when notcommercially available can be readily prepared by one skilled in the artby the acetylation or trifluoroacetylation of the requisite methylketone, R¹COCH₃. Reduction of the nitro derivative 6b to the aniline 6ccan be accomplished in a variety of ways including catalyichydrogenation, treatment with zinc or iron under acidic conditions, ortreatment with other reducing agents such as sodium dithionite orstannous chloride. Subsequently the aniline 6c can be converted to theindeno[1,2-c]pyrazol-4-ones of this invention by acylation followed bytreatment with hydrazine as described previously in Scheme 2.

Another method for making the indeno[1,2-c]pyrazol-4-one ring system isexemplified in Scheme 4. Dimethyl hydrazine was reacted with3-acetylpyridine with no solvent to give the hydrazone 7. This wastreated in a similar fashion as described in Scheme 1 to give thedesired intermediate 8. Additional means of preparing similarintermediates are known to one skilled in the art as described inRappoport, J. Org. Chem. 49:2948-2953, 1984, the contents of which arehereby incorporated herein by reference. This intermediate was carriedthrough the sequence in a similar fashion as described in Scheme 1.

The ureas and semicarbazides (R¹═NHR⁴, X═O) of this invention can beprepared by treating the aniline intermediates in Schemes 1-4, forexample 4 or 6c, with an isocyanate (RNCO) or an aminoisocyanate(RR′NNCO). These reagents are readily prepared in advance by one skilledin the art, or they can be generated in situ employing a precursor, suchas an O-phenylcarbamate (RNHCO₂Ph or RR′NNHCO₂Ph), in the presense ofbase. Alternatively, the ureas and semicarbazides can be prepared bytreatment of the anilines intermediates above with phenyl chloroformatein the presense of base to give an intermediate phenyl carbamate,followed by exposure of the phenyl carbamate to an amine or a hydrazineat elevated temperatures in an appropriate solvent.

The thioureas and thiosemicarbazides (X═S) of this invention can beprepared as described above by treating the aniline intermediates withphenyl thionochloroformate, followed by exposure of the resulting phenylthiocarbamate to the appropriate amine or hydrazine derivative. Thethioamides, thioureas, and thiosemicarbazides can also be prepared fromthe corresponding amides, ureas, and semicarbazides by treatment with areagent such as phosphorous pentasulfide or Lawesson's reagent.

The amidines and guanidines (X═NR) of this invention can be prepared asdescribed in Schemes 1-4 by treatment of the intermediate anilines witha wide variety of reagents known to one skilled in the art. Thesereagents include, but are not limited to, imidates and iminoyl chloridesfor the production of amidines and isothioures and carbodiimides for theproduction of guanidines. Alternatively, the amidines and guanidines ofthis invention can be prepared from the corresponding thioamides,thioureas, and thiosemicarbazides. For example, a thiourea can beS-alkylated by treatment with an akylating agent such as methyl iodideor methyl triflate to provide the corresponding isothiourea. Treatmentof this intermediate with the requisite amine or hydrazine at elevatedtemperatures in an appropriate solvent then provides the desiredquanidine derivative.

Many of the compounds of this invention are synthesized from theindeno[1,2-c]pyrazol-4-ones prepared in Schemes 1-4 by the furthersynthetic elaboration of the R¹ and R² groups. As required the pyrazolering can be protected by a wide range of protecting groups known to oneskilled in the art with the selection of a protecting depending on thechemistry to be employed.

Other features of the invention will become apparent during thefollowing descriptions of exemplary embodiments which are given forillustration of the invention and are not intended to be limitingthereof.

The compounds useful according to the invention optionally are suppliedas salts. Those salts which are pharmaceutically acceptable are ofparticular interest since they are useful in administering the foregoingcompounds for medical purposes. Salts which are not pharmaceuticallyacceptable are useful in manufacturing processes, for isolation andpurification purposes, and in some instances, for use in separatingstereoisomeric forms of the compounds of this invention. The latter isparticularly true of amine salts prepared from optically active amines.

Where the compound useful according to the invention contains a carboxygroup, or a sufficiently acidic bioisostere, base addition salts may beformed and are simply a more convenient form for use; and in practice,use of the salt form inherently amounts to use of the free acid form.

Also, where the compound useful according to the invention contains abasic group, or a sufficiently basic bioisostere, acid addition saltsmay be formed and are simply a more convenient form for use; and inpractice, use of the salt form inherently amounts to use of the freebase form.

The foregoing compounds useful according to the invention may also bemixed another therapeutic compound to form pharmaceutical compositions(with or without diluent or carrier) which, when administered, providesimultaneous administration of a combination of active ingredientsresulting in the combination therapy of the invention.

While it is possible for the compounds useful according to the inventionto be administered alone it is preferably to present them aspharmaceutical compositions. The pharmaceutical compositions, both forveterinary and for human use, useful according to the present inventioncomprise at lease one compound of the invention, as above defined,together with one or more acceptable carriers therefor and optionallyother therapeutic ingredients.

In certain preferred embodiments, active ingredients necessary incombination therapy may be combined in a single pharmaceuticalcomposition for simultaneous administration.

The choice of vehicle and the content of active substance in the vehicleare generally determined in accordance with the solubility and chemicalproperties of the active compound, the particular mode of administrationand the provisions to be observed in pharmaceutical practice. Forexample, excipients such as lactose, sodium citrate, calcium carbonate,dicalcium phosphate and disintegrating agents such as starch, alginicacids and certain complex silicates combined with lubricants such asmagnesium stearate, sodium lauryl sulphate and talc may be used forpreparing tablets. To prepare a capsule, it is advantageous to uselactose and high molecular weight polyethylene glycols. When aqueoussuspensions are used they can contain emulsifying agents or agents whichfacilitate suspension. Diluents such as sucrose, ethanol, polyethyleneglycol, propylene glycol, glycerol and chloroform or mixtures thereofmay also be used.

The oily phase of the emulsions of this invention may be constitutedfrom known ingredients in a known manner. While the oily phase maycomprise merely an emulsifier (otherwise known as an emulgent), itdesirably comprises a mixture of at least one emulsifier with a fat oran oil or with both a fat and an oil. Preferably, a hydrophilicemulsifier is included together with a lipophilic emulsifier which actsas a stabilizer. It is also preferred to include both an oil and a fat.Together, the emulsifier(s) with or without stabilizer(s) make up theemulsifying wax, and the way together with the oil and fat make up theemulsifying ointment base which forms the oily dispersed phase of acream formulation. Emulgents and emulsion stabilizers suitable for usein the formulation of the present invention include Tween® 60, Span® 80,cetostearyl alcohol, benzyl alcohol, myristyl alcohol, glycerylmono-stearate and sodium lauryl sulfate.

If desired, the aqueous phase of the cream base may include, forexample, a least 30% w/w of a polyhydric alcohol, i.e. an alcohol havingtwo or more hydroxyl groups such as propylene glycol, butane 1,3-diol,mannitol, sorbitol, glycerol and polyethylene glycol (including PEG 400)and mixtures thereof. The topical formulations may desirably include acompound which enhances absorption or penetration of the activeingredient through the skin or other affected areas. Examples of suchdermal penetration enhancers include dimethyl sulphoxide and relatedanalogue.

The choice of suitable oils or fats for the formulation is based onachieving the desired cosmetic properties. Thus the cream shouldpreferably be a non-greasy, non-staining and washable product withsuitable consistency to avoid leakage from tubes or other containers.Straight or branched chain, mono- or dibasic alkyl esters such asdi-isopropyl myristate, decyl oleate, isopropyl palmitate, butylstearate, 2-ethylhexyl palmitate or a blend of branched chain estersknown as Crodamol CAP may be used, the last three being preferredesters. These may be used alone or in combination depending on theproperties required. Alternatively, high melting point lipids such aswhite soft paraffin and/or liquid paraffin or other mineral oils can beused. Solid compositions of may also be employed as fillers in soft andhard-filled gelatin capsules using such excipients as lactose or milksugar as well as high molecular weight polyethylene glycols, and thelike.

The pharmaceutical compositions can be administered in a suitableformulation to humans and animals by topical or systemic administration,including oral, inhalational, rectal, nasal, buccal, sublingual,vaginal, parenteral (including subcutaneous, intramuscular, intravenous,intradermal, intrathecal and epidural), intracisternal andintraperitoneal. It will be appreciated that the preferred route mayvary with for example the condition of the recipient.

The formulations can be prepared in unit dosage form by any of themethods well known in the art of pharmacy. Such methods include the stepof bringing into association the active ingredient with the carrierwhich constitutes one or more accessory ingredients. In general theformulations are prepared by uniformly and intimately bringing intoassociation the active ingredient with liquid carriers or finely dividedsolid carriers or both, and then, if necessary, shaping the product.

A tablet may be made by compression or moulding, optionally with one ormore accessory ingredients. Compressed tables may be prepared bycompressing in a suitable machine the active ingredient in afree-flowing form such as a powder or granules, optionally mixed with abinder, lubricant, inert diluent, preservative, surface active ordispersing agent. Moulded tablets may be made by moulding in a suitablemachine a mixture of the powdered compounds moistened with an inertliquid diluent. The tablets may optionally be coated or scored and maybe formulated so as to provide slow or controlled release of the activeingredient therein.

Solid compositions for rectal administration include suppositoriesformulated in accordance with known methods and containing at least onecompound of the invention.

If desired, and for more effective distribution, the compounds can bemicroencapsulated in, or attached to, a slow release or targeteddelivery systems such as a biocompatible, biodegradable polymer matrices(e.g. poly(d,l-lactide co-glycolide)), liposomes, and microspheres andsubcutaneously or intramuscularly injected by a technique calledsubcutaneous or intramuscular depot to provide continuous slow releaseof the compoundis) for a period of 2 weeks or longer. The compounds maybe sterilized, for example, by filtration through a bacteria retainingfilter, or by incorporating sterilizing agents in the form of sterilesolid compositions which can be dissolved in sterile water, or someother sterile injectable medium immediately before use.

Actual dosage levels of active ingredient in the compositions of theinvention may be varied so as to obtain an amount of active ingredientthat is effective to obtain a desired therapeutic response for aparticular composition and method of administration. The selected dosagelevel therefore depends upon the desired therapeutic effect, on theroute of administration, on the desired duration of treatment and otherfactors.

Total daily dose of the compounds useful according to this inventionadministered to a host in single or divided doses may be in amounts, forexample, of from about 0.001 to about 100 mg/kg body weight daily andpreferably 0.01 to 10 mg/kg/day. Dosage unit compositions may containsuch amounts of such submultiples thereof as may be used to make up thedaily dose. It will be understood, however, that the specific dose levelfor any particular patient will depend upon a variety of factorsincluding the body weight, general health, sex, diet, time and route ofadministration, rates of absorption and excretion, combination withother drugs and the severity of the particular disease being treated.

The amount of each component administered is determined by the attendingclinicians taking into consideration the etiology and severity of thedisease, the patient's condition and age, the potency of each componentand other factors.

The formulations may be presented in unit-dose or multi-dose containers,for example sealed ampoules and vials with elastomeric stoppers, and maybe stored in a freeze-dried (lyophilized) condition requiring only theaddition of the sterile liquid carrier, for example water forinjections, immediately prior to use. Extemporaneous injection solutionsand suspensions may be prepared from sterile powders, granules andtablets of the kind previously described.

Administration of a compound of the present invention in combinationwith additional therapeutic agents, may afford an efficacy advantageover the compounds and agents alone, and may do so while permitting theuse of lower doses of each. A lower dosage minimizes the potential ofside effects, thereby providing an increased margin of safety. Thecombination of a compound of the present invention with such additionaltherapeutic agents is preferably a synergistic combination. Synergy, asdescribed for example by Chou and Talalay, Adv. Enzyme Regul. 22:27-55(1984), occurs when the therapeutic effect of the compound and agentwhen administered in combination is greater than the additive effect ofthe either the compound or agent when administered alone. In general, asynergistic effect is most clearly demonstrated at levels that are(therapeutically) sub-optimal for either the compound of the presentinvention or a known anti-proliferative agent alone, but which arehighly efficacious in combination. Synergy can be in terms of improvedinhibitory response without substantial increases in toxicity overindividual treatments alone, or some other beneficial effect of thecombination compared with the individual components.

The compounds of the invention, their methods or preparation and theirbiological activity will appear more clearly from the examination of thefollowing examples which are presented as an illustration only and arenot to be considered as limiting the invention in its scope.

Procedures for evaluating the biological activity of compounds orcompositions according to the invention are carried out as describedherein or by the application or adaptation of known procedures, by whichis meant procedures used heretofore or as described in the literature.

Utility Inhibition of Kinase/Cyclin Complex Enzymatic Activity

Several of the compounds disclosed in this invention were assayed fortheir inhibitory activity against cdk4/D1 and cdk2/E kinase complexes.Briefly, the in vitro assays employ cell lysates from insect cellsexpressing either of the kinases and subsequently their correspondingregulatory units. The cdk2/cyclinE is purified from insect cellsexpressing His-tagged cdk2 and cyclin E. The cdk/cyclin lysate iscombined in a microtitre-type plate along with a kinase compatiblebuffer, ³²P-labeled ATP at a concentration of 50 mM, a GST-Rb fusionprotein and the test compound at varying concentrations. The kinasereaction is allowed to proceeded with the radiolabled ATP, theneffectively stopped by the addition of a large excess of EDTA andunlabeled ATP. The GST-Rb labeled protein is sequestered on aGSH-Sepharose bead suspension, washed, resuspended in scintillant, andthe ³²P activity detected in a scintillation counter. The compoundconcentration which inhibits 50% of the kinase activity was calculatedfor each compound. A compound was considered active if its IC₅₀ wasfound to be less than 1 μM.

Inhibition of HCT 116 Cancer Cell Proliferation

To test the cellular activity of several compounds disclosed in thisinvention, we examined the effect of these compounds on cultured HCT116cells and determined their effect on cell-cycle progression by thecalorimetric cytotoxcity test using sulforhodamine B (Skehan et al. J.Natl. Cancer Inst. 82:1107-12, 1990). Briefly, HCT116 cells are culturedin the presence of test compounds at increasing concentrations. Atselected time points, groups of cells are fixed with trichloroaceticacid and stained with sulforhodamine B (SRB). Unbound dye was removed bywashing and protein-bound dye was extracted for determination of opticaldensity. A compound was considered active if its IC₅₀ was found to beless than 10 μM.
